please solve problem in python.

Problem Three:

Valid Words You now have a large portion of this game complete. Its now necessary to develop a method to test whether the word is valid. There are two criteria. The word must be in the word list. Additionally, the letters need to be in the players hand. Implement the function word_is_valid to return true if both criteria are met and false if either is not met. When you have finished solving this problem, use the testing files test_word_validity. Like the other problems, ensure that develop additional unit tests for any boundaries not assessed.

Problem Four:

Playing Hands The next step is to implement the ability for a user to play with a single hand. Update the function playing_hands to solve this problem. Dont assume there are seven letters in the players hand. To see what you might find in the output from this function, see Figures 3, 4, and 5. This function connects several functions together. Read through the information provided in the skeleton to learn more about the requirements of this function. Make sure that you thoroughly test this function and functions interaction. 7

Problem Five:

Playing a Game A game consists of one-to-many hands. There is one final function needed to complete this game. Delete the code that is present in that function and is not commented. Uncomment the code in the function start_game. No actual programming is necessary to solve this problem, just some deleting and comment toggling. If you would like, you can try to set the hand size to different values when you play the game.
